Teknium 9932366f3c feat(doctor): add Command Installation check for hermes bin symlink
hermes doctor now checks whether the ~/.local/bin/hermes symlink exists
and points to the correct venv entry point. With --fix, it creates or
repairs the symlink automatically.

Covers:
- Missing symlink at ~/.local/bin/hermes (or $PREFIX/bin on Termux)
- Symlink pointing to wrong target
- Missing venv entry point (venv/bin/hermes or .venv/bin/hermes)
- PATH warning when ~/.local/bin is not on PATH
- Skipped on Windows (different mechanism)

Addresses user report: 'python -m hermes_cli.main doesn't have an option
to fix the local bin/install'

10 new tests covering all scenarios.
